SGB Batch Blender with Mitsubishi Controller Page 47 of 118
Operation 5
5-1 SGB Blender Sequence of Operation
1. Blender is started by turning system on or material dropping below level
switch in mix chamber.
2. Metering gates are opened to meter material into the weigh hopper in the
programmed order.
3. Each component is weighed then the batch is dumped into the mix chamber
(provided the mixer “High level” switch is not covered).
4. The material is mixed in the mix chamber and flows into the processing
machine.
5. The optional slide gate below the mixer may control the flow of material to
the molding machine or extruder.
5-2 Quick Start Procedure
1. Calibrate the weigh hopper before running the blender (This will improve
inventory accuracy.).
2. Ensure that all ingredient supply hoppers to be used are filled with material.
Virgin material should be loaded into hopper #1 and regrind into hopper #3.
Note: Hopper #3 is equipped with an oversized square gate to assist in the
feeding of the regrind material.
3. Enter the recipe menu on the LCD panel by turning on the Mitsubishi
controller (It will automatically default to this screen), and enter the blend
recipe desired following the steps listed below:
Touch the box (labeled 1-6) that shows the value you want to
change.
Enter in the new value (0 to 999.99) and hit the enter button (arrow).
After you have entered the new values for all hoppers (1-6), then
push the “Accept New Recipe” button and the recipe will be entered.
The blender monitors the operator’s entries and determines if the recipe entered
is valid before allowing the operator to accept the new recipe. If there is an error
(such as the recipe does not add up to 100% and the blender is in Percentage
Mode) then a message is shown on the Recipe screen to alert the operator of the
problem. The “Accept New Recipe” button is only shown if the recipe is valid and
different from what is currently running on the blender.
